Lenovo ThinkPad W520 Battery
Your Lenovo ThinkPad W520 battery makes your laptop portable so as to work or play anywhere in the house or even outdoors! More amps in a battery basically means the longer it will last when fully charged. Not all batteries are the same, make sure and double-check the part number of the new battery and compare it to the old battery. It is OK to buy a battery with more milliamps, it just means the battery will go further on a single charge. What is truly important is the physical size of the battery as well as the connection.
Subtle cues of a poorly performing primary battery
- The Lenovo laptop will not boot up at all when unplugged
- The laptop does not run longer than one hour before it shuts itself down
- The laptop battery gets puffy and looking like it is going to burst
